Correct, I'm glad you brang this up. The lightened flywheel, under drive pulleys, bigger TB and re-tune on his setup are key to mention beside just the bigger intake/ s2 header upgrade.That video shows clearly how quality parts and the correct combination yields a great output.
Tongman knows this at first hand when his crappy mods were making is car really slow. Then after some suggestion by the members on this forum he went all Skunk2 on I/H and Full Race Exhaust and his ride changed completely. You can see now the great numbers is making in the video.
